“…Conversely, those patients with a high FFR and normal microvascular function (high CFR, low IMR) had excellent outcomes. Thus, based upon this study, abnormal microvascular function may in part explain the worse outcomes in DM patients despite the absence of FFR detected ischemia, as has been recently described in several studies [35–37]. Whether the addition of complementary hemodynamic assessments in DM patients with negative FFR assessments, may result in a more accurate deferred revascularization needs to be studied in larger dedicated studies and the development of repeatable methods of absolute coronary flow measurement may finally help to provide a better understanding of coronary microcirculation [49].…”

“…Conversely in non-DM patients, deferred revascularization appeared to be as safe as reported in prior studies, with low rates of future target vessel MI and TLR. Recently, Liu et al [37] have confirmed these findings and have shown that amongst those patients with an FFR >0.85, diabetics had a more than two-fold higher risk of death and MI than non-diabetics, HR 2.20 (95% CI 1.19–4.01, p = 0.015). In addition, this study also reported that among non-diabetic patients with deferred PCI based upon a FFR >0.80, higher FFR values (closer to 1.0) were associated with lower rates of death, MI and revascularization.…”

Diabetes mellitus (DM) is associated with an excess in cardiovascular morbidity and mortality, and is characterized by increased rates of coronary artery disease. Furthermore, once atherosclerosis is established, this is associated with an increased extent, complexity and a more rapid progression than seen in non-DM patients. Ischemia is the single most important predictor of future hard cardiac events and ischemia correction remains the cornerstone of current revascularization strategies. However recent data suggests that, in DM patients, coronary atherosclerosis despite the absence of ischemia, detected by either invasive or non-invasive methods, may not be associated with the same low risk of future cardiac events as seen in non-DM patients. This review seeks to examine the current evidence supporting an ischemia driven revascularization strategy, and to challenge the notion that ischemia is the only clinically relevant factor in the prediction of cardiovascular outcomes in all-comer DM patients. Specifically, we examine whether in DM patients certain characteristics beyond ischemia, such as microvascular disease, coronary atherosclerosis burden, progression and plaque composition, may need to be considered for a more refined risk stratification in these high-risk patients.

“…Based upon the results of landmark trials, deferred revascularization in those lesions with a FFR >0.80 is associated with a low risk of future adverse cardiac outcomes . However, more recently, several studies have shown that deferred revascularization based on FFR assessment of intermediate lesions in high risk patients and specifically in DM patients may not be as safe and is associated with worse outcomes than in non‐DM patients .…”

“…Whilst fractional flow reserve (FFR) has an extensive evidence base, a low proportion of patients with DM were included in the landmark studies . Recent evidence has suggested that deferred revascularization based upon FFR in DM patients may not be associated with a similar low risk of MI or target lesion revascularization as seen in non‐DM patients . Whilst risk prediction models have been developed to better predict the risk of FFR‐guided deferred lesion failure (DLF), such models may not be as applicable in DM patients, given the significantly different nature of atherosclerosis seen in this condition .…”

“…Comparing FFR-guided deferred revascularization in patients with and without diabetes, Kennedy et al also showed that those with diabetes were associated with a significantly higher rate of target lesion failure [29]. Accordingly, a recent study by Liu et al showed that a higher FFR was associated with lower rates of death, myocardial infarction and revascularization among non-diabetic patients with deferred PCI, but in diabetic patients with deferred revascularization, FFR was not able to differentiate the risk of cardiovascular events [30]. …”

BackgroundAdenosine-free coronary pressure wire metrics have been proposed to test the functional significance of coronary artery lesions, but it is unexplored whether their diagnostic performance might be altered in patients with diabetes.MethodsWe performed a post-hoc analysis of the CONTRAST study, which prospectively enrolled an international cohort of patients undergoing routine fractional flow reserve (FFR) assessment for standard indications. Paired, repeated measurements of all physiology metrics (Pd/Pa, iFR, contrast-based FFR, and FFR) were made. A central core laboratory analyzed blinded pressure tracings in a standardized fashion.ResultsOf 763 subjects enrolled at 12 international centers, 219 (29%) had diabetes. The two groups were well-balanced for age, clinical presentation (stable or unstable), coronary vessel studied, volume and type of intracoronary contrast, and volume of intracoronary adenosine. A binary threshold of cFFR ≤ 0.83 produced an accuracy superior to both Pd/Pa and iFR when compared with FFR ≤ 0.80 in the absence of significant interaction with diabetes status; indeed, accuracy in subgroups of patients with or without diabetes was similar for cFFR (86.7 vs 85.4% respectively; p = 0.76), iFR (84.2 vs 80.0%, p = 0.29) and Pd/Pa (81.3 vs 78.9%, p = 0.55). There was no significant heterogeneity between patients with or without diabetes in terms of sensitivity and specificity of all metrics. The area under the receiver operating characteristic (ROC) curve was largest for cFFR compared with Pd/Pa and iFR which were equivalent (cFFR 0.961 and 0.928; Pd/Pa 0.916 and 0.870; iFR 0.911 and 0.861 in diabetic and non-diabetic patients respectively).ConclusionscFFR provides superior diagnostic performance compared with Pd/Pa or iFR for predicting FFR irrespective of diabetes (clinicaltrials.gov identifier NCT02184117).
